Add butter and pulse until the mixture holds together when you squeeze it, with pecan-sized lumps of butter still visible.

Mix the egg and milk, and add it to the dough, mixing just until everything is cohesive.

Divide the dough in half. Wrap in plastic, and refrigerate for up to 2 days or for 30 minutes.

Remove the chilled dough from the refrigerator and allow it to soften and become workable, about 15 to 30 minutes.

Place one piece on a lightly floured work surface, and roll it into a rectangle about ⅛" thick, large enough that you can trim it to an even 9" x 12". Laying a 9" x 13" pan atop the dough will give you an idea if you’ve rolled it large enough. Trim off the edges; place the scraps on a baking sheet, and set them aside, along with the 9" x 12" rectangle of dough.

Roll the second piece of dough just as you did the first. Press the edge of a ruler into the dough you’ve just rolled, to gently score it in thirds lengthwise and widthwise; you’ll see nine 3" x 4" rectangles.

Beat the egg, and brush it over the entire surface of the dough. Place a heaping tablespoon of filling into the center of each marked rectangle.

Place the second sheet of dough atop the first, using your fingertips to press firmly around each pocket of jam, sealing the dough well on all sides.

Brush the tops of the pastry with the remainder of the egg and then sprinkle the wheat germ and raw sugar topping on top of your tart.

Press the tines of a fork all around the edge of the rectangle. Cut the dough evenly in between the filling mounds to make nine tarts. Press the cut edges with your fingers to seal, then press with a fork, to seal again.

Gently place the tarts on a lightly greased or parchment-lined baking sheet. Prick the top of each tart multiple times with a fork; you want to make sure steam can escape, or the tarts will become billowy pillows rather than flat toaster pastries. Refrigerate the tarts (they don’t need to be covered) for 30 minutes, while you preheat your oven to 350°F.

Remove the tarts form the fridge, and bake them for 25-28 minutes, until they’re a light golden brown. Remove them from the oven, and allow them to cool on the pan.
